Machine Description:

*NAIGOO N40 8AXIS hobbing machine is equipped with a Higgerman (or Siemens 828D) 8-axis CNC system that can be used to manufacture gear shafts and pinions (straight teeth, helical teeth, conical teeth, etc.) by spreading or indexing.

* Axis feed Z-axis consists of Z and Z1 axis, which can be moved separately or simultaneously, making product loading and unloading easier and laying the foundation for automation.

* Workpiece worktable and tailstock worktable use 2 axes (C and C1) to rotate synchronously, so that the work piece is more solid when double top machining.

* Compact machine structure, a variety of automation applications, especially suitable for small and micro gear batch processing.

Machine Features:

■ Fully CNC using the Higerman or Syntec CNC system, each axis of the machine tool for CNC control and B, C, X, Z as the linkage axis, by the electronic gear box (program) to complete the cutting tooth tooth movement, feed compensation motion, differential feed compensation motion, Increased the function of the machine tool (such as rolling small taper and drum gear become very simple); By shortening the transmission chain, the positioning accuracy and repeated positioning accuracy of each axis can be improved through numerical control compensation after using semi-closed loop or full closed loop control, so as to improve the machining accuracy and CP value of the machine tool and increase the reliability of the machine tool. When changing varieties, the time of calculating and changing the gear hanging wheel and the differential hanging wheel, feeding and the spindle shifting are eliminated, thus reducing the auxiliary processing time and increasing the flexibility of the machine tool.

■ High efficiency machine has high tool spindle speed and high worktable speed, greatly improve the cutting efficiency; It is suitable for high speed cutting with multi-head hob with strong cutting capacity and high processing efficiency. Double and multi-coupling gears with different modules, different numbers of teeth, different helical angles and different helical directions can be used to complete the tooth rolling in a single installation, and can also be used for single degree milling.

■ High precision adopts a large number of imported famous brand accessories to improve the speed, accuracy and reliability of the machine tool. High precision has high rigidity linear guide rail, ball screw, rolling bearing, precision spindle, servo motor and numerical control technology with pre-loading, so that the accuracy of the machine tool can be guaranteed and improved under the condition of high speed machining;

S best vibration-absorbing effect: the high rigidity of the casting lathe bed, and with the use of preloading, no gap of the ball screw drive feed system and imported roller type damping and load of the linear rolling guide, do not need to maintain and keep a long time of high precision, indexing table with eliminate worm gear and worm pair clearance and damping mechanism;

■ Functioned composite workpiece can be completed in a single clamping process, so as to improve the processing efficiency and accuracy of the workpiece, such as: automatic feeding, gear hobbing, secondary gear hobbing, multi-process gear hobbing, deburring, automatic blanking;

■ High degree of automation with automatic feeding, feeding  automatic clamping device, 24 hours continuous working ability;

Environmentally friendly installation of oil mist separator, so that the discharge is only oil-free fog;

Intelligent and information digital control technology, sensor technology, information technology and network control technology together to make the intelligent level of CNC gear machining machine tools higher. It can realize the functions of error compensation, collision prevention, overload protection, tooth meshing, machining allowance distribution, tool wear, zero programming interface, multi-functional processing software, automatic identification, remote control and remote diagnosis when the robot is moving the workpiece between machine tools.

■ High flexibility to achieve short preparation time for mass production;

■ High cost performance
